Mold for concrete burial-vaults.



WILLIAM G. LERCH, OF EASTON, PENNSYLVANIA.

MOLD FOR CONCRETE BURIAL-VAULTS.

Specification of Letters Patent.

Application filed February 25, 1915. Serial No. 10,594.

To all whom it may concern:

Be it known that I, WVILLIAM G. LERCH, a citizen of the United States, residing at Easton, in the'county of Northampton and State of Pennsylvania, have invented a new and useful Mold for Concrete Burial-Vaults, of which the following is a specification.

The present invention relates to improvements in a mold for concrete burial vaults, one object of the invention being the provision of a novel mold, in which the core mold for the vault proper is composed of a plurality of sections which are connected together by means of miter joints so that the sections may be readily slipped into and out of position during the setting up and the collapsing of the mold.

A further object of the present invention, is the provisionof a novel construction of severalmolds, in which there are provided attachment means forguiding'and holding the cement in place during the initial pouring and coalescing thereof.

A still further object of the invention, is the provision of a mold of this character which is simplified in construction so as to render the setting up and collapsing of the same more easy, and yet at the same time provide a rigid structure when once erected so as to properly hold the concrete during the pouring process and while coalescing so that there is no tendency for the same to be bulged or in fact in any way injured, to the damage of thefinal product.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawingsFigure 1 is a' top plan of the complete vault mold assembled. Fig. 2 is a sectional view taken on line 22 of Fig. 1 a portion of the core mold being broken away to show the position of one of the ends and one ofthe sides relatively to the bottom section or support of the com? plete mold. Fig. 3 is a transverse sectional view through the complete apparatus. Fig. 4 is an inverted perspective of one of the bottom forming sections of the core mold. Fig. 5 is a fragmental perspective of the re.

ceptacle portion of the vault and showing the lugs which maintain the casket or cofiin above the bottom. I

Referring to the drawings, the numeral 1 designates the base of the receptacle portion of the mold, the same being a rectangular member and having a rectangular opening 1 so as to provide an open supporting member including an inner flange 2 and an outer flange 3 defining a rectangular recess 1, the purpose of which will presently appear.

The core mold 5 comprises two side sections each one of which is composed of members 6 and 6 out upon an angular line as at 7 and mitered so that such'sections may be readily slipped into place during the assembling of the core mold 'or be readily collapsed when removing such sections. The short ends of the core mold are made in two sections 8 and 8 out upon the miter line 9 as illustrated in Figs. 1 and 3, so that such sections are also easily placed into position in assembling the mold or readily collapsed when removing the same.

The sections 10 and 10 constitute the members for formingthe inside of the bottom of the vault and such sections are beveled to. provide the V-shaped recesses 11, which in turn as illustrated in the formed vault receptacle V of Fig. 8, provide the V-shaped cross ribs 11*, so that the casket or coffin will be supported above the bottom of the vault. Each of the respective sections 10 and 10 as illustrated in perspective in Fig. 1, is provided with strips 12, which fit within the opening formed by the side sections 6 and 6 and the end sections 8 and 8. Connected to. the under side of the strips 12 is a strip 13, which forms a handle whereby the sections 10 may be manipulated in setting up or collapsing the mold.

It will be noted that the lower end edges of the sections 6-6 and 8-8 are disposed to rest with their inner faces flush against the inner edges of the flange 2 of the base 1 and thattherefore the edges rest fully within the recesses 4, so that the rim o with the recessed portion o of the vault V is properly formed and held in place so as to rest in the recess 4:, which in reality constitutes the bottom of the mold.

The outer mold consists of two longitudinal plates 14 and two oppositely disposed inclined end plates 16, the respective base engaging portions 15 and 17 of which are Patented Dec. 1 1, 1915.

reduced so as to rest within the recess 4 and abut against the outer flange 3 of the base as clearly illustrated in Figs. 2 and 3. Fastening devices (not shown), attach the side members 14 to the end members 16, while in addition, in order to prevent the sections posing the tie bolts 18 when the same are drawn upon to clamp the members 14 rigidly in place upon the end sections 16. At the corners of the respective sections 14 and 16 are disposed quarter round sections 23, which assist in forming the corners for the vault V, while sealing the concrete contacting surfaces of the core mold 5 and also the incasing mold composed of the members 14 and 16 are sheets 24 of galvanized or other non-corrosive metal. i In assembling the present mold, the base 1 is placed upon the horizontal surface, and a core mold 5 is properly positioned, as illustrated in Figs. 1 and 2, after which the outer mold composed of the plates 14 and 16 is set up, as illustrated, the lower edges thereof fitting as do the lower edges of the core mold 5 within the rectangular recess 4 of the base 1. Thus, a space is provided between the adjacent walls of the inner core and the outer mold sections so that the concrete may be properly poured, the necessary reinforcements where desired being placed in proper position between such molds. In order to assist in properly spacing the core mold from the outer mold member, a plurality of spacing members S are provided and as the concrete is poured, the spacing members are pulled vertically upward from between the members of the mold. The concrete is filled to a predetermined distance above the sections 10 and 10 and properly troweled to produce the desired flatness upon the bottom of the vault V. The same when thus finished is permitted to stand a suflicient period of time to properly coalesce, after which the outer sections 14 and 16 are removed by withdrawing. them upwardly, while the sections of the core mold are collapsed from the inside due to the peculiar arrangement of the miterjoints 7 and 9 of the sections, or the completed article may be lifted from above and without collapsing the core mold.
